To all whom t may concern.'

Be it known that 1,' Eiin'syvoirrrrv L. Pann- 'r1ss,"a citizen-ot the' United States, residing at Los Angeles, in the county of' Los Angelesk 5 and State (if-California, have'inv'ented'cer? tain new and-useful Improvements-finL Dual TWheels for 'Vehiclesof which the `following is a specification..

My invention relates to dual-Wheelshor l0 vehicles, moreparticula'rly to thatfclas's of Wheels tprovided 'with pneumatic tires'ivhich need toy be removed when {puncture'ch 'and E'the objects of'my invention are?v First, to provide a Adiialivheel for vehlcles l5 in which thetire andl rim may be readily changed on either the'inner or" outer Wheel members. Second', to` provide 1a.' valiee'lff.l thisclass in which -tlie outer Wheel membermay be removed lbythe removing ofsixnuts 0 and fwhich provides ready acces's'tothe inl' ner Wheel-so that theytire and-'ri'mmay be readily removediroi'n the inner Wheel porW tion. Third, to provide a dual Wheel in which conventional spare tires and rims 35, beuse'd. Fourth, to providea'iiovellyyooiiir Structed dual' Wheel;l }4`-iftli',7tov provide a dual WheelofV thisfclass inf'vvh'ich the por` tions-supporting the tires may befspacedv so,

that the tires are spaced from elacli otherz dual Wheel of this classwhi'ch is very-simple and economicalol construction` durable, ef! i'icient, easy ot f operation forv changing the tires and` which will not readily"deteriorate or get out of order.

vWith these andother obyects in View as Will'appear hereinafter, my-L invention consists of certain novel features of construction, combination and arrangement of parts and portionsas will be hereinafter'described in detail andV particularly lsetiorth'in' the appendedlolaims, reference being liad to the accompanying drawings: and tov Ethe'1 `lohara'ctiers of reference thereon, wvhich'form a part of this application, in'ivhich:

It will benherejnoted that ty eri'ms 8 and't) 'andgtirfes and11Aarefoftlieordif" nary o1' conventional typejot` spare;y tires I, and

rims and are supported in y the conventional mannel-'by'mean'zs of split rims `6 and 7- Which 8 0 are oft the convenvtionaltype and by bolts 4.' and the'clamp'tmeinbers 5, which areavlso ot -theioonventional The ce'vntralportion out the'innerv Wheel -member 1 is provided Withv a bore 1d' Iinwhich the conventional 8 5 skein, bearingsy and axle may1 be mounted1 in' i the usual manner. Mounted orf the sliein 15 is the oiiter Wheel member stipportl14 which is provided With aiil'oiitiva'rdl yextending flange-14'n its iniier side `Aand. vv'ith sup- 90 Aporting ledges 14" andy 14C. It will be noted that the ledge: is aboiit one-eighth:4 ofan inch less fin diaineterfthan 'the l`ledge 141 so that the v'vheelmember 121112155 be readilyy positioned over the member 14`as'shown best 95 in Fig. 1 ofthe drawings. This member 14 is supported' in positionl relatively to the member, 1f by'melanshof a plurality. of bolts 3, in 'tliis'easef I haveshown siii, ""Tliese bolts are provided with enlarged portions 3 in-` IUU y CII termediate their ends, the one side of which enlarged portion butts against the flange portion 14fL and the extended end passes through the wheel member 1 and hub flange 2 and is provided with a nut 3 on its inner ond, thus providing means for clamping the member 14 against the outer face of the wheel member 1, as shown best in Fig. 1 of the drawings. Mounted on the member 14 is the outer wheel member 12 which 1s provided with an extended bearing and portion 121 which rests on the ledge 14c and the opposite side of the wheel member 12 rests on the ledge 14d. This member 12 is provided with holes conformnig with the holes in the member 1 so that the bolts 3 which are extended from the large portion 3a pass through the member 12 and are supported by means of nuts 3b. It will be noted that the member 12 is provided with enlarged recesses adapted for receiving the enlarged portion 3 of the bolts 3, thus providing means for rigidly clamping the wheel member 12 in position in connection with the members 1 and 14, as shown best in Fig. 1 of the drawings. The perimeter of the outer wheel member 12 is the same as that of the wheel member 1, hereinbefore described, and supports the rim 9 and tire 11 in the same manner as hereinbefore described. rIhis outer Wheel member 12 is provided with cut away portions and with flanges, as shown best in Fig. 3 of the drawings, to lighten the wheel member.

IVhen it is desired to change the outer tire the usual procedure is all that is necessary, that of removing the nuts from the bolts 4 and removing the key ring? then talring the tire and rim from the wheel and placing another in its place. When it is desired to change the inner tire the nuts 3b are removed from the bolts 3 after which the wheel member 12 together with the tire and rim can be shifted outwardly off of the member 14. rFhen the nuts on bolts 4 and clamps 5 are removed and the key ring 6 removed thus proceeding in the usual manner and another tire and rim placed in position, after which the wheel member 12, together with its rim and tire may be placed back into position on the bolts 3 and the nuts 31D placed on the ends of the bolts 3, thus clamping the outer Wheel member 12 in position relatively to the members 1'- and 14.

Though I have shown and described a particular construction, combination and arrangement of parts and portions I do not wish to be limited to this particular construction, combination and arrangement Ibut desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In dual vehicle wheels, a wheel member secured to the hub and provided on its periphery with the conventional spare tire and rim securing means and provided with a. plurality of holes through said member, an outer wheel member support provided with an extending flange provided with holes conforming with the holes in said wheel member and provided with two diameter ledges in spaced relation adapted to be secured to the hub of the wheel, a plurality' of bolts provided with enlarged portions adapted to rest against said flange and pass through the first mentioned wheel member provided with nuts on their opposite ends adapted to clamp said support to said rst mentioned wheel member, an outer wheel member provided with a ledge portion adapted to rest on the outer ledge on said support and provided with enlarged recesses and bolt holes adapted to receive the enlarged portions of said bolts and provided on its periphery with the conventional tire and rim supporting means.

2. In a dual wheel for Vehicles, an inner wheel member provided with a plurality of bolt holes concentric therewith, spaced from its perimeter some dist-ance, an outer wheel supporting member provided with a flange provided with holes conforming with the holes in said first mentioned wheel member, a plurality of bolts provided with enlarged portions intermediate their ends, one side of which is adapted to rest against said flange and clamp said flange against said first mentioned wheel member and an outer wheel member provided with holes adapted to fit the extended ends of said bolts and fit snugly on said wheel supporting member and be clamped thereon by the extended ends of said bolts.

3. In dual wheels for vehicles, an inner wheel member, an outer wheel member, an intermediate support for said outer wheel member provided with a flange extending between said wheel members and a plurality of bolts extending through said wheel members and said flange adapted to clamp said wheel members and said outer wheel supporting member in rigid relation to each other.

4. In dual wheels for vehicles, an inner wheel member, an outer wheel member, an intermediate support for said outer wheel member provided with a flange extending between said wheel members, a plurality of bolts extending through said wheel members and said flange adapted to clamp said wheel members and said outer wheel supporting member in rigid relation to each other and hub means secured to the inner side of the inner wheel member and to the outer side of the outer wheel member support.

5. In dual Wheels for vehicles, an inner wheel member, an outer Wheel member, an intermediate support for said outer Wheel member provided With a ange extending between saidrwheel members, a plurality of bolts extending through said Wheel member and said flange adapted to clamp said Wheel members and said 4outer Wheel supporting member in rigid relation to each other and conventional means for securing the eon- 10 ventional spare tire and rim on the periphery of both said inner and outer Wheel members.

In testimony whereof, vI have hereunto set my hand at Los Angeles, California this 25th day of February 1925.
